LEDs (Light Emitting Diodes) are used in a wide variety of applications across many different industries, and are now becoming increasingly popular in both commercial and domestic contexts. The ELM 3-250 is the latest in the range of cost effective small size specialist LEDs specifically designed for applications in small spaces. This article will provide an overview of the ELM 3-250’s application field and working principle.

Application Field

The ELM 3-250’s ability to be used in smaller spaces makes it suitable for a variety of applications. This includes:

• Downlighting
• Security Lighting
• Retail Lighting
• Display Lighting
• Pathway Lighting

The ELM 3-250 has a very low-profile design and its slim structure makes it particularly suitable for recessed lighting. This shape and size also makes it an ideal choice for smaller enclosed spaces, such as tight corners, storage areas and basement walkways. The ELM 3-250 is also ideal for replacement lighting equipment, where traditional lighting is not suitable.

Spacers/Standoffs

In order to maintain the longevity and performance of the ELM 3-250 LED, it is important to use correct mounting and placement of LED spacers/standoffs. The use of spacers/standoffs helps to ensure the LED is kept the right distance away from its heat sink, helping to dissipate heat and boosting the lifetime of the LED.

The recommended spacer/standoff for the ELM 3-250 is the Stalux Spacer, as this is specifically designed for use with the ELM 3-250 and ensures precise heat dissipation and even temperature distribution across the LED’s casing.

Working Principle

The working principle of the ELM 3-250 LEDs involves the movement of electrons across its semiconductor material, known as the P-N junction. When the LED is switched on, electrons move from the N-type material to the P-type material and release energy in the form of light. This process is known as electroluminescence.

As with most LED designs, the ELM 3-250 has a constant current driver circuit. This ensures that the LED consistently produces light output at its targeted voltage, regardless of the variances in current flow. The constant current driver circuit also extends the lifetime of the LED, as it prevents the LED from being damaged by overcurrent or short circuits.

Conclusion

The ELM 3-250 is a specialist LED that is ideal for applications in small spaces. Its application field includes downlighting, security lighting, retail lighting, display lighting and pathway lighting.

Spacers/standoffs are also essential for the ELM 3-250 as they help to ensure the LED is kept the right distance away from its heat sink. The Stalux Spacer is recommended for use with the ELM 3-250. Finally, the working principle of the ELM 3-250 is based on the P-N junction and it has a constant current driver circuit, which helps to produce consistent light output and increases the lifetime of the LED.
